After Month's of searching i have finally found a working a/c compressor.My cousin is a fridgy and took this home for me we decided it the other day and removed the a/c case and took out the compressor.

This compressor will be used at 400-450psi.

Still to attach.-450psi Gauge.-On & Off.-Compressor to gun fitting's.-Case for all the wired.

If the shop is well equipped, you can replace the large accumulator with a more reasonable fitting. If you have a welding torch, the joint on the bottom is hard silver brazed. Set the torch to a carborizing flame (adjust for neutral and then reduce oxygen for a large feather 1/2 the size of the envelope and heat the joint to cherry red. The silver will melt and the piece can be easily lifted off. Reworking joints and making repairs with those connections is not hard with the right tools. Warning, the oil in the sytem will vaporize in the area of the joint. Flow argon, dry Nitrogen, or CO2 to prevent an explosion when the oil reaches ignition temperature. Use safety equipment. Silver brazing skills is a good skill to have if you work with AC.

The dull grey brownish solder looking stuff is hard silver solder and is used at brazing temperatures. A torch flame low on oxygen is used to remove copper oxides during the brazing process so no flux is required. The lack of flux keeps the inside of the system clean with no residue to plug up expansion valves and filter dryers.

Update, added photo of common solders.On the left is lead free plumbing solder. On the middle is electrical solder, which is very soft, and a rod of silver brazing solder on the right. The hard rod is used for high pressure AC work. The rod in the photo is 15% silver.
